I am not sure I understand your question at all. Since I dont live in Brooklyn, what do you want us to do? You could extrapolate your argument to a situation in which a child is murdered. We all can state our outrage, but we are not going to be able to catch the murderer. So, I dont understand where you are coming from at all.
Your self righteous outrage has accomplished exactly nothing of benefit for the nurse, the thug or anyone else. Not one positive thing whatsoever. All you have done is to sow dissension on the forum which is the common result of all politically correct mush-headed liberal compassion.
